RESUMO

OBJECTIVE@#To investigate the detection rate and hematologic phenotype of HKαα thalassemia in south Guangxi, in order to provide reference for the prevention and control of thalassemia and prenatal and postnatal care consultation in this region.@*METHODS@#Gene testing was performed on pre-marital medical examinations, pre-pregnancy eugenic health examinations, prenatal examinations and hospitalized thalassemia-positive persons in south of Guangxi, and the results were analyzed.@*RESULTS@#A total of 183 190 thalassemia patients were included in this study, the age was mainly concentrated in 26-35 years old (101 709 cases, accounting for 55.521%), and 40 HKαα mutations were detected, detection rate was 0.022%, including 5 cases in Nanning, 22 cases in Qinzhou, 2 cases in Fangchenggang, 11 cases in Beihai. A total of 29 ethnic groups were included in the survey, but HKαα gene was observed only in Han nationality (0.0380%) and Zhuang nationality (0.0068%). A total of 8 genotypes carrying HKαα mutations were detected in this study ( HKαα/--SEA, βN/ βN, HKαα/αα, β-28/ βN, HKαα/αα, β-50/ βN, HKαα/αα, βCD17/ βN, HKαα/αα, βCD27/28/β N, HKαα/αα, βCD41-42/ βN, HKαα/αα, βCD71-72/ βN, and HKαα/αα, βN/ βN). Except for most cases with HKαα/αα, βN/ βN genotypes with no significant changes in the hematological indexes, mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) of other genotypes were decreased, showing microcytic hypochromic performance, mild anemia or no anemia.@*CONCLUSION@#HKαα carrier is often misdiagnosed as -α3.7 carrier, which easily leads to missed diagnosis or misdiagnosis. Therefore, it is necessary to continuously improve the diagnostic level of laboratory testing personnels and genetic counselors to avoid unnecessary interventional puncture operations and birth of children with moderate and severe thalassemia.

RESUMO

OBJECTIVE@#To investigate the gene mutation and genotype distribution of thalassemia in the population of childbearing age in Chongzuo area of Guangxi.@*METHODS@#Six α-thalassemia and 17 β-thalassemia gene mutations common in Chinese were detected by gap-polymerase chain reaction (gap-PCR) combined with agarose gel eletrophoresis and reserve dot bolt hybridization in 29 266 cases of child-bearing age suspected of thalassemia.@*RESULTS@#A total of 19 128 (65.36%) cases were identified with thalassemia. The detection rate of α-thalassemia, β-thalassemia and α-combining β-thalassemia was 45.25% (13 242/29 266), 15.47% (4 526/29 266) and 4.65% (1 360/29 266), respectively. A total carrying rate of 8 kinds of α-thalassemia gene mutations was 26.74% (15 649/58 532), including 12.51% for --SEA, followed by 5.70% for -α3.7, and 0.24% for --Thai. Among 32 α-thalassemia genotypes, the most common five were --SEA/αα, -α3.7/αα, αCSα/αα, -α4.2/αα and αWSα/αα, accounting for 47.27%, 18.31%, 8.56%, 8.52% and 7.91%, respectively, as well as 0.97% for --Thai/αα. A total carrying rate of 13 kinds of β-thalassemia gene mutations was 10.07% (5 897/58 532), including 3.63% for CD41-42, followed by 2.55% for CD17, and 0.003% for -50 (G>A). Among 17 β-thalassemia genotypes, the most common six were CD41-42/N, CD17/N, CD71-72/N, CD26/N, 28/N and IVSI-1/N, accounting for 36.15%, 25.81%, 9.43%, 8.18%, 8.09% and 7.75%. The homozygous genotype CD26/CD26 [hemoglobin (Hb): 121 g/L] and -28/-28 (Hb: 56 g/L) were respectively detected in one case, and double heterozygous genotype were detected in 5 cases, including 3 cases of CD41-42/CD26 (Hb: 41 g/L, 51 g/L, 63 g/L, respectively), 1 case of -28/IVSI-1 (Hb: 53 g/L), and 1 case of CD71-72/CD26 (Hb: 89 g/L), in which patients with moderate or severe anemia had a history of blood transfusion. Among 104 α-combining β-thalassemia genotypes, the most common were --SEA/αα, -α3.7/αα combining CD41-42/N and --SEA/αα combining CD17/N, accounting for 12.13%, 9.63% and 9.26%, respectively. In addition, 1 case of --SEA/-α3.7 combining -28/IVSI-1 (Hb: 83 g/L) and 1 case of -α3.7/αα combining CD41-42/ CD41-42 (Hb: 110 g/L) were detected without history of blood transfusion, while 1 case of αWSα/αα combining CD41-42/CD17 (Hb: 79 g/L) and 1 case of --SEA/αα combining CD17/-28 (Hb: 46 g/L) were detected with history.@*CONCLUSIONS@#The detection rate of thalassemia genes is high and the mutations are diverse in the population of childbearing age in Chongzuo area of Guangxi. The common deletion genotype is --SEA/αα in α-thalassemia and CD41-42/N in β-thalassemia, and deletion genotype --Thai is not rare. There is a certain incidence of intermediate and severe β-thalassemia, and most patients require transfusion therapy. The results are beneficial for genetic consultation and intervention of thalassemia.

RESUMO

Objective: To investigate the clinicopathological features of perivascular epithelioid cell tumor (PEComa) of the lung. Methods: Eight PEComa cases of the lung diagnosed at the First Affiliated Hospital of Soochow University, Suzhou, China from July 2008 to December 2021 were collected and subject to immunohistochemical staining, fluorescence in situ hybridization and next generation sequencing. The relevant literature was reviewed and the clinicopathological features were analyzed. Results: There were 5 males and 3 females, aged from 18 to 70 years (mean 39 years). There were 3 cases of the right upper lung, 3 cases of the left lower lung, 1 case of the left upper lung and 1 case of the right middle lung. Seven cases were solitary and 1 case was multifocal (4 lesions). Seven cases were benign while one was malignant. The tumors were all located in the peripheral part of the lung, with a maximum diameter of 0.2-4.0 cm. Grossly, they were oval and well circumscribed. Microscopically, the tumor cells were oval, short spindle-shaped, arranged in solid nests, acinar or hemangiopericytoma-like patterns, with clear or eosinophilic cytoplasm. The stroma was rich in blood vessels with hyalinization. Coagulated necrosis and high-grade nuclei were seen in the malignant case, and calcification was seen in 2 cases. Immunohistochemically, the tumor cells were positive for Melan A (8/8), HMB45 (7/8), CD34 (6/8), TFE3 (4/7), and SMA (3/8). All cases were negative for CKpan and S-100. TFE3 (Xp11.2) gene fusion was examined using the TFE3 break-apart fluorescence in situ hybridization in 5 cases, in which only the malignant case was positive. The next generation sequencing revealed the SFPQ-TFE3 [t(X;1)(p11.2;p34)] fusion. Follow-up of the patients ranged from 12 to 173 months while one patient was lost to the follow-up. The malignant case had tumor metastasis to the brain 4 years after the operation and then received radiotherapy. Other 6 cases had no recurrence and metastasis, and all the 7 patients survived. Conclusions: Most of the PEComas of the lung are benign. When there are malignant morphological features such as necrosis, high-grade nuclei or SFPQ-TFE3 gene fusion, close follow-up seems necessary.

RESUMO

OBJECTIVES@#To study the characteristics of amino acid metabolism in preterm infants in Guangxi, China.@*METHODS@#A retrospective analysis was performed on the medical data of 30 757 neonates who underwent the screening for inherited metabolic diseases and had negative results in Guangxi Neonatal Disease Screening Center from 2018 to 2020. Among these neonates, there were 28 611 normal full-term infants (control group) and 2 146 preterm infants (preterm birth group). According to gestational age, the preterm infants were further divided into four groups: very preterm (n=209), moderately preterm (n=307), and late preterm group (n=1 630). According to birth weight, they were divided into three groups: very low birth weight group (n=161), low birth weight group (n=1 085), and normal birth weight group (n=900). According to blood collection time, they were divided into three groups: 3-7 days group (n=1 664), 8-14 days group (n=314) and 15-28 days group (n=168). Tandem mass spectrometry was performed to measure the levels of 11 amino acids in dried blood spots, which were then compared between groups.@*RESULTS@#After adjustment for confounding factors, there were significant differences in the levels of 11 amino acids among different gestational age groups (P<0.05), and significant differences were observed in the levels of the 11 amino acids between the control group and the various preterm groups (except for citrulline and methionine in the late preterm group). There were significant differences in the levels of 11 amino acids among different birth weight groups (P<0.05). Except for ornithine, there were significant differences in the levels of other amino acids among the different blood collection time groups (P<0.05).@*CONCLUSIONS@#Gestational age, birth weight and blood collection time all affect amino acid metabolism in preterm infants in Guangxi, China. This provides a basis for the laboratory to establish the reference standard and clinical interpretation of blood amino acid levels in preterm infants, and to improve the nutritional metabolism of preterm infants.

RESUMO

OBJECTIVE@#To study the expression levels of glial cell line-derived neurotrophic factor family receptor α-1 (GFRα1) and enhancer of zeste homolog 2 (EZH2) in the intestinal tissue of children with Hirschsprung's disease (HSCR), as well as the role of EZH2 in the regulation of GFRα1 gene expression and the pathogenesis of HSCR.@*METHODS@#The samples of colon tissue with spasm from 24 children with HSCR after radical treatment of HSCR were selected as the experimental group, and the samples of necrotized colon tissue from 18 children with neonatal necrotizing enterocolitis after surgical resection were selected as the control group. Real-time PCR and Western blot were used to measure the expression levels of GFRα1 and EZH2 in colon tissue in both groups. Human neuroblastoma SH-SY5Y cells were divided into an EZH2 over-expression group and a negative control group. The cells in the EZH2 over-expression group were transfected with pCMV6-EZH2 plasmid, and those in the negative control group were transfected with pCMV6 plasmid. The expression levels of EZH2 and GFRα1 were measured after transfection.@*RESULTS@#Compared with the control group, the experimental group had significant reductions in the mRNA and protein expression levels of GFRα1 and EZH2 in colon tissue (P<0.05), and the protein expression of EZH2 was positively correlated with that of GFRα1 (r=0.606, P=0.002). Compared with the negative control group, the EZH2 over-expression group had significant increases in the expression levels of EZH2 and GFRα1 after SH-SY5Y cells were transfected with EZH2 over-expression plasmid (P<0.05).@*CONCLUSIONS@#Low expression of EZH2 in the colon tissue of children with HSCR may be one of the causes of inadequate expression of GFRα1 and onset of HSCR.

RESUMO

Background: 4-coumarate:CoA ligase (4CL) plays an important role at the divergence point from general phenylpropanoid metabolism to several branch pathways. Although 4CL sin higher plants have been extensively studied, little has known about the 4CL gene of bamboo. Results: In current study, a Na4CL gene putative encoding 4-coumarate:CoA ligase (4CL) and its 5’-flanking region were isolated from bamboo (Neosinocalamus affinis) by RACE-PCR and genomic DNA walker, respectively. Na4CL encodes a predicted protein of 557 amino acids, with conserved motifs of adenylate-forming enzymes. Phylogenetic analysis showed that Na4CL shared 62~85 percent identity with other known plant 4CLs, and cluster closely with some known 4CLs in monocots. Sequence analysis revealed conserved cis-acting elements (Box A and AC-II element) present in the Na4CL promoter. Additionally, a Na4CL RNAi construct was transformed into tobacco. Transgenic tobaccos displayed significant down-expression of endogenesis 4CL and reduced lignin contents. Conclusion: These results contribute to the knowledge of the presence of Na4CL gene and its possible role in phenylpropanoid metabolism.

RESUMO

<p><b>OBJECTIVE</b>To investigate the radiosensitizing effect and its mechanism of 3-MA in human hypopharynx cancer cells.</p><p><b>METHODS</b>5 mmol/L of 3-MA combined with 2 Gy or 4 Gy of X-ray was utilized to deal with Fadu cells, and the cell livability (cloning efficiency) and DNA lesion severity (tail moment) of each groups was examined by clonogenic survival assay and comet assay, then differences were compared between groups by independent-sample T test. Fadu cells were then treated with different dose of 3-MA (1, 2, 5, 10 mmol/L), the alteration of cell cycle distribution was detected by flow cytometer, and differences among groups were analyzed through one-way analysis of variance. The expression of p62 and cyclinB1 in each group was examined by western blot.</p><p><b>RESULTS</b>The livability and DNA lesion severity of cells treated with 3-MA alone showed no notable variation. Compared with non-3-MA groups, the cloning efficiency of cells treated with 3-MA decreased much more after irradiated with 2 Gy or 4 Gy of X-ray (t = 13.41 or 13.98, P < 0.001), and the cells showed a more serious DNA lesion (t = 7.07 or 6.91, P < 0.001). The G2/M percentages of cells in the control group and groups treated with 1, 2, 5, 10 mmol/L of 3-MA were 17.10 ± 1.20, 23.30 ± 2.3, 39.90 ± 3.12, 58.47 ± 1.65, 76.13 ± 3.51 and differences among groups were statistically significant (F = 278.4, P < 0.05). The expression of p62 in cells treated with 3-MA showed a dose-dependent increase, while cyclinB1 showed a dose-dependent decrease.</p><p><b>CONCLUSIONS</b>The autophagy inhibitor 3-MA could enhance radiosensitivity of human hypopharynx cancer cells by inducing G2/M arrest and enhancing irradiation-induced DNA damage.</p>

RESUMO

Objective To comprehensively measure the burden of hepatitis B, liver cirrhosis and liver cancer in Shandong province, using disability-adjusted life years (DALYs) to estimate the disease burden attribute to hepatitis B virus (HBV)infection. Methods Based on the mortality data of hepatitis B, liver cirrhosis and liver cancer derived from the third National Sampling Retrospective Survey for Causes of Death during 2004 and 2005, the incidence data of hepatitis B and the prevalence and the disability weights of liver cancer gained from the Shandong Cancer Prevalence Sampling Survey in 2007, we calculated the years of life lost (YLLs), years lived with disability (YLDs) and DALYs of three diseases following the procedures developed for the global burden of disease (GBD) study to ensure the comparability. Results The total burden for hepatitis B, liver cirrhosis and liver cancer were 211 616 (39 377 YLLs and 172 239 YLDs), 16 783 (13 497 YLLs and 3286 YLDs) and 247 795 (240 236 YLLs and 7559 YLDs) DALYs in 2005 respectively, and men were 2.19, 2.36 and 3.16 times as that for women, respectively in Shandong province. The burden for hepatitis B was mainly because of disability (81.39%). However, most burden on liver cirrhosis and liver cancer were due to premature death (80.42% and 96.95%). The burden of each patient related to hepatitis B, liver cirrhosis and liver cancer were 4.8, 13.73 and 11.11 respectively. Conclusion Hepatitis B, liver cirrhosis and liver cancer caused considerable burden to the people living in Shandong province, indicating that the control of hepatitis B virus infection would bring huge potential benefits.

RESUMO

<p><b>OBJECTIVE</b>To evaluate the clinical use of acellular dermal matrix (ADM) in the repair of pharynx.</p><p><b>METHOD</b>From June 2003 to December 2004, 18 cases of laryngopharyngeal carcinoma or oropharyngeal carcinoma accepted treatment of surgery. Four of them had the tumor in the place of posterior wall of laryngopharynx or oropharynx. In the operation, the tumor was resected and the function of larynx was reserved, reconstruction of the posterior wall of laryngopharynx or oropharynx was made with ADM. Three of them had normal function of vocal cords and the tumor was in the place of posterior wall of pharynx and lateral wall of piriform fossa. These patients accepted resection of the tumor and the larynx was reserved. ADM was sutured to the prevertebral fascia to repair the pharynx, reinforcement was made with sternocleidomastoid muscle then. The other 11 patients had the tumor in the pharynx and cervico-esophagus and the vocal cords were fixed. These cases accepted total resection of the larynx and laryngopharynx. ADM was sutured to the prevertebral fascia to repair the posterior wall of laryngopharynx, musculo-cutaneous flap of pectoralis major muscle was made to repair the anterior and lateral walls. All these 18 patients accepted radiotherapy after the operation, the dosage was 60-70 Gy.</p><p><b>RESULTS</b>Among all these 18 cases, no rejection of ADM or formation of pharynx fistula happened after the operation. The allograft became normal mucosa finally. Two patients had subcutaneous infection. After the treatment of dressing change and antibiotics, the wound healing was satisfying. All the 18 patients had resumption of oral diet finally but 3 of them had light mis-swallowing. Seven patients whose larynx were reserved had the trachea cannula pulled out The follow-up periods after the operation lasted 12 months to 30 months. The middle follow-up period was 19. 38 months. Neither rejection nor scar formation of the allograft happened. The follow-up of 11 patients lasted more than 18 months, 3 of them had relapse of tumor. After the second operation 1 patient was still alive and 2 patients died of distant metastasis.</p><p><b>CONCLUSION</b>ADM can be easily obtained. Its histocompatibility were perfect The operative procedure were easy to perform. The complications of donor part can be totally avoided. The combined use of ADM and musculo-cutaneous flap of pectoralis major muscle or other neck tissue was safe and effective in the reconstruction of pharynx.</p>

Using Fisch stage: thirty three cases were in stage I and II, 22 cases via palatal approach, 11 cases via endoscopic surgery;18 cases were in stage IIN and IV, 9 cases via lateral rhinotomy approach, 4 cases via midfacial degloving approach + Lefort I approach or modified maxillotomy, 5 cases via craniofacial approach. Twenty three cases accepted the embolization of the artery which feed the tumor, 7 cases in stage IV, 8 cases in stage IlI, 5 cases in stage II, 3 cases in stage I.</p><p><b>RESULTS</b>The average of blood loss was 1010 ml in operation but it became 200 - 870 ml (the average of blood loss was 485 ml) when had a selective preoperative embolization. The blood loss of none selective preoperative embolization was 500 - 3500 ml (the average of blood loss was 1600 ml), t = 7. 48, P < 0.05, the average of blood loss of selective preoperative embolization is less than the average of blood loss of none selective preoperative embolization. After 9 to 48 months of operation (the average time was 26.4 months), 8 cases recurred one time and 2 cases recurred two times.</p><p><b>CONCLUSIONS</b>The preoperative embolization could reduce the amount of bleeding during operation. In patients who are in stage I and II, searching endoscopic surgery could avoid the effect on craniofacial development which traditional surgical procedure did. For patient who are in stage III and IV, midfacial degloving approach and Lefort I approach or modified maxillotomy are not only good for exclusive resection of the tumor but also have less effect on articulation and beautiful cosmetic outlook.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the incidence of cases with rash and fever illness (RFIs) after measles vaccine (MV) inoculation.</p><p><b>METHODS</b>During 1999 to 2002, 150 RFIs cases reported by the special measles surveillance system in Shandong province, China, were investigated and analyzed epidemiologically.</p><p><b>RESULTS</b>7 674 690 ml MV were distributed during 1999 to 2002 and the annual average incidence of RFIs cases after MV inoculation was 0.20/10 000 ml (0.2 ml per dose). There was significant difference of incidences each year (chi(2) = 10.13, P < 0.05). All RFIs cases were sporadically distributed without epidemiological links. Clinical symptoms showed that 88.67% of the 150 RFIs cases having > 38.5 degrees C fever and 75.33% of all cases appeared typical rash after 4 to 11 days (the medium was 8 days) after MV inoculation. The order of rash onset among RFIs cases was consistent with that of regular measles cases caused by wild virus. 68.67% of the RFIs cases had first MV inoculation and 94.71% were 8 to 12 month-olds. IgM sera antibody test from RFIs cases were rubella negative and 45.65% positive for measles.</p><p><b>CONCLUSION</b>RFIs due to allergic reaction or measles vaccine virus infection might occur after MV inoculation. There seemed to be a correlation between RFIs incidence and the doses of MV. Measles virus genotype analysis needs to be carried out to confirm if the onset of some RFIs cases is aetiologically associated to MV vaccine virus infection.</p>
